Homeowners could make up to £3,000 a year just by renting out their driveway to electric car owners.
The extra cash was highlighted in new research by Halfords and rental site Stashbee.
They say charges range from £5 to £10 a day, all the way up to £3,000 a year - although the exact amount you could make does vary.
For example, it depends on how often you rent out your driveway and which part of the UK you live in.
If you’re situated near a desirable location, such as a commuter train station, you’re more likely to earn more out of your driveway.
Property owners could add at least 20% to potential charges if their driveway includes an electricity source, Halfords and Stashbee said.
Richard Bruce, Halfords motoring director, said: “We believe that private drive - ways could be one of the ways the UK can bridge the electric charging gap.
“Infrastructure on trunk roads is definitely heading in the right direction, but progress is slower in residential areas where roadside charging is more of a challenge.

“Getting homeowners to rent out their driveways and charging units could make a meaningful contribution to solving the problem.”
Websites such as YourParkingSpace and JustPark.com allow drivers to rent out their driveways to other road users.

It comes as drivers are being urged to switch to electric cars, with the sale of new petrol and diesel vehicles to be banned from 2030.
This deadline has been pushed forward from 2040 to help lower carbon emissions in the UK.
Rising fuel prices - which hit 167p a litre for petrol on Sunday, and 179p a litre for diesel - have helped accelerate the demand for electric cars.
Some 10,417 battery electric vehicles (BEVs) were registered in February.
This is up 196.3% on a year ago when there were 3,516 registrations, and 402.6% higher than February 2020 when 2,508 registrations were made.
But the move to electric has still been met with concerns, as the UK only has 15% of the electric vehicle charging points it needs to meet its net zero target by 2050.
And concerns about where to charge is the biggest concern stopping Brits from ditching their petrol and diesel vehicles, according to the Department for Transport.
Back in December 2020, Prime Minister Boris Johnson announced £1.3billion to accelerate the rollout of electric vehicle charging points in homes, streets and motorways.
